I brought a 600sx with only one test flight from a guy, but I finger out there is a little tail wag on that. After that, I purchase a new Quick UK tail rotor set, and install it but tail wag is still on.
I have tail gain 90 on vbar.
Could any one help me figer out the wrong thing?

I had to spend some time with the Quick UK tail to get it working smoothly. Even just a little resistance would make a wag. Gain had little to no effect. I gently filed the inside (the portion the brass bushing passes through), I gently sanded the sides (the part the brass bushings pass though) I very carefully used loctite, being sure not to get any in the linkage.
I've also damaged the Brass collar before too when swapping one out (the one you tighten with 7mm wrench) It was not damage that I could see, but it had resistance when sliding on the shaft - it too made a wag.

Best of luck.

yeah I just ordered new part of stock rotor and want to see if it works

I had a similar issue with my brand new 550sx. Gyro gain helped a little but couldn't get rid of the wag. Turns out that after looking at everything over again I had the tail rotor spinning the wrong way Tail is rock solid now. Coming from a blade 450x I was under the assumption that the belt twist was clockwise.
